Abstract: The present disclosure discloses a mobile terminal and an antenna device for same. The antenna device includes: a primary antenna and a first metal component. The primary antenna is disposed on the bottom of a mobile terminal and includes: a first antenna branch; a second antenna branch; and a first feed point. The first feed point is connected to a first end of the first antenna branch and a first end of the second antenna branch. The first feed point is connected to a mainboard of the mobile terminal. The first metal component is located on the bottom of the mobile terminal and includes a first metal segment, a second metal segment, and a third metal segment. The first metal segment, the second metal segment, and the third metal segment are sequentially arranged in a horizontal direction. The first metal segment and the third metal segment are connected to a metal rear case of the mobile terminal.

Abstract: An electronic device and an antenna of an electronic device are provided. The electronic device includes a metal shell, and the antenna includes: a radiating surface formed by metal shell and having a slot group penetrated therethrough in an up and down direction of the metal shell, the slot group including a plurality of slots; a medium filling layer including a body part disposed on a lower surface of the metal shell and a plurality of filling parts disposed on an upper surface of the body part and filled in the plurality of slots respectively; and an excitation sheet disposed on a lower surface of the medium filling layer.

Abstract: An electric device includes a metal shell having a back metal shell part and a first side metal shell part, and a first antenna which includes: a first radiating surface formed by the back metal shell part and the first side metal shell part and having a variant T-shaped group of slots and a first L-shaped slot, a part of the variant T-shaped group of slots being formed in the back metal shell part, and the other part thereof being formed in the first side metal shell part, the first L-shaped slot being formed in the first side metal shell part; a first dielectric sheet disposed on a front surface of the back metal shell part; and a first L-shaped feeder disposed on a front surface of the first dielectric sheet.
